Capital cities are politico-administrative centers. They are command centers, they symbolize authority and also the unit that is governed. Primarily they are capitals of states, but other governance systems may also have capitals. In the European context there are now regional capital cities and at least the concept of a European capital. Particularly on account of their symbolic function but also for the uses made of its appearance in political life, the cityscape of capital cities is an interesting topic for research. There are different types of capital cities in Europe that give rise to different cityscapes. Existing urban networks and types of political regime are important in this respect. Although cityscapes are pretty stable, they are differently perceived over time and uses made of them also change. A research agenda for this intersection of historical, cultural and political geography should concentrate on the evolution of these cityscapes, their perception and the uses made of them in the acting out of politics. 相似文献
Although a global cap-and-trade system is seen by many researchers as the most cost-efficient solution to reduce greenhouse gas (GHG) emissions, the governments of developing countries refuse to enter into such a system in the short term. Many scholars and stakeholders, including the European Commission, have thus proposed various types of commitments for developing countries that appear less stringent, such as sectoral approaches. A macroeconomic assessment of such a sectoral approach is provided for developing countries. Two policy scenarios in particular are assessed, in which developed countries continue with Kyoto-type absolute commitments, while developing countries adopt an emissions trading system limited to electricity generation and linked to developed countries' cap-and-trade systems. In the first scenario, CO2 allowances are auctioned by the government, which distributes its revenues as a lump sum to households. In a second scenario, the auction revenues are used to reduce taxes on, or to give subsidies to, electricity generation. The quantitative analysis, conducted with a hybrid general equilibrium model, shows that such options provide almost as much emissions reduction as a global cap-and-trade system. Moreover, in the second sectoral scenario, GDP losses in developing countries are much lower than with a global cap-and-trade system, as is also the effect on the electricity price. 相似文献
A conceptual-stochastic approach to short time runoff data modelling is proposed, according to the aim of reproducing the
hydrological aspects of the streamflow process and of preserving as much as possible the dynamics of the process itself. This
latter task implies preservation of streamflow characteristics at higher scales of aggregation and, within a conceptual framework,
involves compatibility with models proposed for the runoff process at those scales. At a daily time scale the watershed response
to the effective rainfall is considered as deriving from the response of three linear reservoirs, respectively representing
contributions to streamflows of large deep aquifers, with over-year response lag, of aquifers which run dry by the end of
the dry season and of subsurface runoff. The surface runoff component is regarded as an uncorrelated point process. Considering
the occurrences of effective rainfall events as generated by an independent Poisson process, the output of the linear system
represents a conceptually-based multiple shot noise process. Model identification and parameter estimation are supported by
information related to the aggregated runoff process, in agreement to the conceptual framework proposed, and this allows parameter
parsimony, efficient estimation and effectiveness of the streamflow reproduction. Good performances emerged from the model
application and testing made with reference to some daily runoff series from Italian basins. 相似文献
Geopolitical changes combined with the increasing urgency of ambitious climate action have re-opened debates about justice and international climate policy. Tensions about historical responsibility have been particularly difficult and could intensify with increased climate impacts and as developing countries face mounting pressure to take mitigation action. Climate change is not the only time humans have faced historically rooted, collective action challenges involving justice disputes. Practices and tools from transitional justice have been used in over 30 countries across a range of conflicts at the interface of historical responsibility and imperatives for collective futures. Central to this body of theory and experience is the need to reflect both backwards- and forwards-oriented elements in efforts to build social solidarity. Lessons from transitional justice theory and practice have not been systematically explored in the climate context. This article conceptually examines the potential of transitional justice practices to inform global climate governance by looking at the structural similarities and differences between the global climate regime and traditional transitional justice contexts. It then identifies a suite of common transitional justice practices and assesses their potential applicability in the climate context.
POLICY RELEVANCE
Justice disputes, including about historical responsibility and future climate actions, are long-standing in the climate context and could intensify with increased climate impacts and broadened mitigation pressures.
Lessons from efforts to use transitional justice mechanisms could provide insight into strategies for balancing recognition of harms rooted in the past, while creating stronger future-oriented collective action.
Several areas of transitional justice practice including: the combination of amnesties and litigation, truth commissions, reparations and institutional change could provide useful insights for the climate context.
